I added a barrel "bushing" to cover the "illegal" threads on my post-ban build. I simply did not want to permanently mount a compensator. My result looks very much like a basic crowned post-ban barrel. The photos are here.HarryD

You obviously have an ISP (AOL is not an ISP), then do you have "personal" web space on their public web server? If so, up load the pictures you want to there then link them to the posts you want. If not, you'll have to find a "free" picture posting place or someone willing to let you use their space.
The directions for adding images are in the [b]Board Code[/b] section:

Images: enclose the address with {img} and {/img}.
You can align an image to the right or left by adding it to the tag as follows: {img=right} and {/img=right} or {img=left} and {/img=left}
